GPT-5.6-Sol's Autonomous Voxel Manhattan Sparks Debate

Recently, the GPT-5.6-Sol model has sparked discussion within the AI community for autonomously completing a complex 3D modeling task. Developer @mattshumer_ demonstrated that the model ran autonomously for nearly a week with minimal human intervention, ultimately generating a complete voxel-based 3D Manhattan in one go. This showcase has triggered conversations about the model's ability to execute complex tasks over extended periods, accompanied by scrutiny and skepticism from professional perspectives.

Key Details and Reactions

@mattshumer_ emphasized the high precision of the result, noting that his previous prompting methods for Fable are equally applicable to GPT-5.6-Sol to achieve high-quality outputs. Reposts pointed out that this performance aligns with METR's time-span curves for long-duration autonomous tasks. However, the demo also faced professional pushback. Critics like @nptacek mocked the output, suggesting that the developers should understand "z-fighting" (a common rendering glitch) before publishing 3D demos, implying that the generated 3D scene still contains technical flaws.
